Any criticism of the reproduction of the paper’s methodology should go right back to the original author, because the original author of the paper did not adequately document the methodology used. Then when asked directly to provide the methodology, the authors did not provide the methodology.
A cornerstone of valid science is reproducibility. Even if the original author’s methodology is sound, we cannot know because we cannot reproduce it, ergo, it’s basically bunk science.
When we take out all of the “both sides” political motivations driving a lot of the discussion in this thread, the glaring lack of scientific rigor falls squarely on the original authors, regardless of the topic. Extraordinary claims require extraordinary evidence, and it’s the responsibility of the original authors to provide that evidence, not the people providing the takedown.
